3rd Gen Tacoma Tire Sizes (2016-2023)

What tire sizes did the 3rd gen Tacoma come with?

This is the first Tacoma generation our OEM fitment dataset reaches, and it reaches most of it: 7 of the 8 third-gen model years have real trim rows — 21 rows in total, across 10 distinct trim labels. The year missing is 2016, the generation's first, which sits one year before the dataset starts.

The rows are grouped the way the sources grouped them: 2017-2020, 2021-2022, and 2023 are 3 row sets, not 7. Where several model years share one set, no source ever separated them at the trim level, and splitting them here would invent precision. 2021-2022 and 2023 carry year-specific Toyota sourcing; 2017-2020 does not.

How big are the 3rd-gen factory sizes in inches?

Push the 4 third-gen sizes through the parser and something unusual falls out: they are all the same height. P245/75R16 at 30.5 in, P265/60R18 at 30.5 in, P265/65R17 at 30.6 in, and P265/70R16 at 30.6 in — a total spread of 0.14 in from shortest to tallest. Four sizes, three wheel diameters, one rolling height.

That looks deliberate rather than accidental. Sidewall drops from 7.3 in on the 16-inch fitment to 6.3 in on the 18-inch one, and the rim grows by precisely enough to compensate. Revolutions per mile stay inside a 3-count band, so moving between third-gen factory sizes leaves the speedometer, the effective gearing, and the ABS calibration essentially untouched.

Width tells the same story from the other side. 3 of the 4 sizes share an identical 10.4 in section width; only P245/75R16 is narrower, at 9.6 in. What separates one third-gen factory fitment from another is the wheel it is wrapped around, not the tire's footprint on the road.

What is the max tire size on a 3rd gen Tacoma?

The third gen is the generation the aftermarket built its 33-inch reputation on, and the fitment matrix is the only place in this repo that puts numbers to it. This generation gets all 4 lift tiers — one of only two that do — and its stock ceiling, 265/70R17, already sits a full inch above every size the factory shipped.

• 265/75R16 is the no-rub 'holy grail' on 16s. True 33s do not fit stock.
• 285/70R17 (33s) fits street-only with fender-liner trim + heat gun, but rubs off-road at full lock.
• The classic 3rd-gen move: 3 in lift + 33s + 0/negative offset.
• Budget for a spare-tire relocation and speedometer recalibration.

The gap between the leveling tier and the 3-inch tier is the one that costs money. The modeled ceiling moves only 0.5 in between them, from 275/70R17 to 285/70R17, but the clearance work goes from removing mud flaps to a cab mount chop plus aftermarket upper control arms, and a 4.56-4.88 regear enters the picture. Height is cheap on this platform right up until the last half inch.

Which upgrade sizes fit a 3rd gen Tacoma?

Every one of the 21 upgrade sizes our size pages cover fits a third-gen wheel diameter, and every one of them lands somewhere on this generation's ladder — nothing in the catalogue is beyond what the model will place. That is unique among the four generations, and it is entirely down to the 4-6 inch tier reaching 35.0 in.

The distribution is the thing to read: 8 sizes inside the stock ceiling, 1 at the leveling tier, 4 at the 3-inch tier, and 8 needing 4-6 inches. Every 33- and 35-inch flotation size in the catalogue sits in that last group, which is why so many third-gen builds stop at 285/70R17: it is the last size before the ladder's expensive step.

What does a size change do to a 3rd-gen speedometer?

The flat factory height that makes this generation's four sizes interchangeable also sets a trap, because the moment you leave them the error arrives all at once. Below, every factory size and every modeled ceiling is measured against 265/70R16 — the size the most third-gen rows we hold actually ship.

Between the four factory sizes the worst error is well under half a percent, so a wheel-and-tire swap inside the factory set needs no correction at all. The ladder is a different story: the stock-height ceiling already reads 3.3% fast, and the 4-6 inch ceiling 14.4%. At that top figure an indicated 60 is really 69 mph, and the same proportion is being shaved off every mile the odometer records.

3rd gen Tacoma fitment quirks the data actually shows

The list below comes out of the 21 trim rows themselves. Where the rows do not support a claim — real-world rub reports, per-truck offsets, cab mount measurements — it is not here.

• All 21 third-gen rows write the size with the P-metric prefix (P245/75R16, P265/65R17, P265/70R16, and P265/60R18). Not one fourth-gen row does. P-metric marks a passenger-rated size, and the prefix vanishing at the generation change is the most visible textual difference between the two size sets in this dataset.
• Wheel diameters run 16 in, 17 in, and 18 in, and the smallest of them carries the most trucks: the 2 16-inch sizes account for 13 of the 21 rows, more than the 17- and 18-inch sizes combined. On this generation a bigger wheel means a road-biased package, not a more capable one.
• P265/70R16 alone appears on 8 of the 21 rows — the off-road-oriented trims across all 3 year groups share one size and one wheel diameter.
• 6 of the 21 rows are package- or configuration-dependent rather than plain standard fitments, including named appearance packages that change the wheel finish while leaving the tire size untouched.
• 4 rows are recorded as "likely standard" rather than standard — every one of them in the 2017-2020 span. The table above prints that wording as the dataset wrote it, because the hedge is the finding: those trims were never mapped to a size by a year-specific document.
• Only 1 third-gen row names a factory tire brand (Goodyear Kevlar on the Trail Special Edition). Every other row records a tire type, not a model, so no page here will tell you which brand your truck shipped on.
• 2017-2020 holds 5 rows, 2021-2022 holds 8 rows, and 2023 holds 8 rows. The row count per span measures how much detail that source carried, not how much the truck changed.

3rd gen Tacoma tire sizes year by year

7 third-gen model years have their own page here, each showing that year's own rows, its trim links, and the same computed geometry. 2017, 2018, 2019, and 2020 carry a verification caution on their pages for the reason given above. 2016 has no page, because it has no rows.

• 2023 tire sizes
• 2022 tire sizes
• 2021 tire sizes
• 2020 tire sizes
• 2019 tire sizes
• 2018 tire sizes
• 2017 tire sizes

4 of the 3rd-gen factory sizes have their own size pages — 245/75R16, 265/60R18, 265/65R17, and 265/70R16 — with full dimensions, revolutions per mile, and every Tacoma trim in our data that ships them.

Working out your own 3rd-gen tire size

Most third-gen tire questions come down to a single comparison — the factory size against the one you want — so start there and let the calculator show you what changes. If you are weighing a lift at the same time, run the estimator first and shop sizes second.

• Read the tire and loading placard in the driver's door jamb — on a 2016-2023 truck that is the only per-vehicle source, and it outranks every table on this page.
• Check the sidewall of the tire actually fitted: on a 2016-2023 truck it is often not the size the charts above predict, because previous owners change sizes and rarely update anything else.
• Put your 3rd-gen factory size and whatever you are considering into the tire calculator together — diameter, section width, revolutions per mile, and speedometer error all move as one.
• Run the 3rd-gen generation, your lift, and your wheel offset through the max tire size estimator before you buy rather than after, and compare its answer to the 4-tier ladder above.
